Abstract

The method involves pressing a reel from a pressing roller into a winding bed (8) in an initial phase of a winding process. The reel is ejected from the winding bed after reaching a final- reference diameter with reduced winding speed under separation of a material web. A new material web top developed by the separation is wound on a new sleeve (12) inserted into the winding bed. The new sleeve is inserted into an area that is limited by two supporting rollers (6, 7), and the reel permits geometric relationships of the area and the sleeve. An independent claim is also included for a device for winding a material web on a sleeve in a winding bed.

Description

Die Erfindung betrifft ein Verfahren zum Aufwickeln einer Materialbahn auf mindestens eine in einem aus zwei Tragwalzen gebildeten Wickelbett liegende Hülse, wobei der entstehende Wickel wenigstens in der Anfangsphase des Wickelprozesses von einer Andruckwalze in das Wickelbett gedrückt wird und nach Erreichen eines End-Solldurch-messers wenigstens bei reduzierter Wickelgeschwindigkeit unter Abtrennung der Materialbahn aus dem Wickelbett ausgestoßen wird, und der durch die Abtrennung entstandene neue Materialbahnanfang anschließend auf mindestens eine neue in das Wickelbett eingebrachte Hülse aufgewickelt wird.The invention relates to a method for winding a web on at least one sleeve lying in a winding bed formed from two support rollers, wherein the resulting winding is pressed at least in the initial phase of the winding process by a pressure roller in the winding bed and after reaching an end target diameter at least is ejected at reduced winding speed with separation of the material web from the winding bed, and the resulting by the separation of new material web start is then wound on at least one new introduced into the winding bed sleeve.

Ferner betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens.Furthermore, the invention relates to a device for carrying out the method.

Die Erfindung wird im folgenden anhand einer Rollenwickelvorrichtung, insbesondere einer Rollenschneidvorrichtung, für Papier- und Kartonbahnen beschrieben. Sie ist aber in ähnlicher Weise auch auf Verfahren bzw. Vorrichtungen anwendbar, auf denen Rollen mit anderen Bahnen vergleichbarer Eigenschaften gewickelt und/oder geschnitten werden.The invention will be described below with reference to a roll winding device, in particular a roll cutting device, for paper and board webs. However, it is similarly applicable to methods and apparatuses on which rolls are wound and / or cut with other webs of comparable properties.

Nach ihrer Herstellung werden Papier- und Kartonbahnen zu Rollen aufgewickelt. Diese auch als Maschinen- oder Mutterrollen bezeichneten Rollen erreichen mittlerweile Breiten bis über 11.000 mm und Durchmesser bis zu 4.000 mm. Mit derartigen Abmessungen sind sie meist nicht in den Verkehr bringbar. Zu diesem Zweck müssen sie zuvor in sogenannte Kunden- oder Fertigrollen verwandelt werden. Das geschieht auf Rollenschneidmaschinen, die aus einer Abwicklung für die erwähnten Mutterrollen, einer Einrichtung zum Längsschneiden der abgewickelten Bahn und einer Aufwicklung bestehen, in der die entstandenen Einzelbahnen zu Fertigrollen aufgewickelt werden. Die Kundenrollen haben im fertigen Zustand Durchmesser im Bereich von 400 mm bis 2.500 mm und Breiten in der Größenordnung von 300 bis 4.500 mm. Aus der Mutterrolle werden in den Rollenschneidmaschinen also in einem einzigen Arbeitsgang mehrere Kundenrollen gleichzeitig erzeugt. Für die simultan gewickelten Einzelrollen wird häufig auch der Begriff "Kundenrollensatz" verwandt. Aus dem erwähnten Verhältnis von Mutterrollendurchmesser zu Kunderrollendurchmesser folgt, dass ein und dieselbe Mutterrolle für mehrere Fertigrollensätze "gut" ist. Bei den Rollenschneidmaschinen unterscheidet man zwei Grundtypen, den Doppeltragwalzenwickler und den Stützwalzenwickler. Bei ersterem, auf den allein sich die Erfindung bezieht, liegen auf zwei achsparallelen Tragwalzen soviel Hülsen in axialer Richtung nebeneinander im Wickelbett als Teilbahnen geschnitten werden. Damit die Einzelbahnen auf die jeweiligen Hülsen aufgewickelt werden können, müssen die Einzelbahnanfänge auf den Hülsen festgelegt werden. Zu diesem Zweck sind die Hülsen regelmäßig mit einem doppelseitigen Klebeband oder ähnlichem versehen. In die randständigen Hülsen des Hülsensatzes greift während des gesamten Wickelprozesses ein Hülsenführungskopf ein, der den Hülsen- bzw. den entstehenden Fertigrollensatz "zentriert" hält. Den Fertigrollen möchte man eine bestimmte Wickelstruktur verleihen. Die Rollen sollen regelmäßig im Inneren härter gewickelt sein als in ihrem Umfangsbereich. Mit anderen Worten, die Wickelhärte soll von innen nach außen abnehmen. Ein solcher Wickelhärteverlauf lässt sich ohne geeignete Maßnahmen nicht realisieren. Zu Beginn des Wickelvorgangs bestehen die Einzelrollen nämlich praktisch nur aus den Wickelhülsen. Sie sind dann noch so leicht, dass die aus ihrem Gewicht resultierenden Kräfte in den beiden Nips zwischen den Rollen und den Tragwalzen zur Erzeugung der Soll-Wickelhärte nicht ausreichen. Es ist daher bekannt, den Einzelrollensatz zu Beginn des Wickelvorgangs mittels einer auf seiner Scheitellinie aufgesetzten Belastungswalze mit zusätzlicher Kraft in das Wickelbett zu drücken; mit wachsendem Durchmesser und damit zunehmendem Gewicht der Einzelrollen wird diese Zusatzkraft natürlich gezielt zurückgefahren.After their production paper and board webs are wound into rolls. These rolls, also referred to as machine or master rolls, now reach widths of more than 11,000 mm and diameters of up to 4,000 mm. With such dimensions they are usually not marketable. For this purpose, they must first be converted into so-called customer or finished rolls. This is done on slitter-winder machines, which consist of a processing for the mentioned parent rolls, a device for longitudinal cutting of the unwound web and a winding consist, in which the resulting individual webs are wound up to finished rolls. The customer rolls in the finished state have diameters ranging from 400 mm to 2,500 mm and widths of the order of 300 to 4,500 mm. From the mother roll, several customer roles are generated simultaneously in the slitter-cutting machines in a single operation. The term "customer roll set" is often used for the simultaneously wound single rolls. It follows from the aforementioned ratio of master roll diameter to customer roll diameter that one and the same master roll is "good" for several finished roll sets. In the case of the slitter-winder one distinguishes between two basic types, the double-take-up roll winder and the back-up roll winder. In the former, to which the invention alone refers, are on two axially parallel support rollers as much sleeves in the axial direction next to each other in the winding bed as part webs are cut. So that the individual tracks can be wound onto the respective sleeves, the single-track starts on the sleeves must be determined. For this purpose, the sleeves are regularly provided with a double-sided adhesive tape or the like. In the marginal sleeves of the sleeve set engages a sleeve guide head during the entire winding process, which holds the sleeve or the resulting finished roll set "centered". The finished rolls want to give a certain winding structure. The rollers should be regularly wrapped harder inside than in their peripheral area. In other words, the winding hardness should decrease from the inside out. Such a winding hardness curve can not be realized without suitable measures. At the beginning of the winding process, the single roles are practically only from the winding tubes. They are then so light that the forces resulting from their weight in the two nips between the rollers and the support rollers to produce the desired winding hardness are not sufficient. It is therefore known to press the single roll set with additional force into the winding bed at the beginning of the winding process by means of a load roller placed on its crest line; With increasing diameter and thus increasing weight of the single rollers, this additional force is of course deliberately reduced.

Wie oben erwähnt, lassen sich aus ein und derselben Mutterrollen fast immer mehrere Fertigrollensätze produzieren. Man geht dabei wie folgt vor: Hat der aktuelle Fertigrollensatz nahezu seinen Solldurchmesser erreicht, so wird die Arbeitsgeschwindigkeit über eine vorgegebene Rampe auf 0 m/min reduziert. Kurz vor Erreichen des Stillstands - bei Eintritt des Stillstandes entspricht der Ist-Durchmesser der Fertigrollen natürlich dem Soll-Durchmesser - schlägt man die Einzelbahnen ab, deren Enden im Nachlauf noch auf den jeweiligen Rollen festgelegt werden. Alsdann wird bei stillstehender Anlage der fertige Kundenrollensatz aus dem Wickelbett ausgestoßen und ein neuer Hülsensatz in das freigewordene Wickelbett eingebracht - vgl. z.B. DE 43 34 029 C2 . Erst wenn das geschehen ist, kann ein neuer Wickelprozess beginnen. Der Fachmann fasst diese Vorgänge unter dem Begriff "Set- oder Wurf-Wechsel" zusammen. Es leuchtet ein, dass diese Setwechsel Zeit kosten und die Produktivität der Rollenschneider herabdrücken. Um die negative Auswirkung zu verdeutlichen, folgendes Beispiel: Findet beim Rollenschneiden durchschnittlich alle 6 Minuten ein Set-Wechsel statt - diese Ziffer ist durchaus praxisnah - , so ergibt sich im 24-Stundenbetrieb bereits die beträchtliche Zahl von 240 Set-Wechseln. Auf ein Betriebsjahr hochgerechnet kommt es demnach zu etwa 85.000 kleinen "Produktionsausfällen", was sich bei einer Dauer von 20 sec pro Set-Wechsel jährlich zu rd. 20 Tage "Produktionsunterbrechung" aufaddiert.As mentioned above, it is almost always possible to produce several finished sets of rolls from one and the same parent roll. The procedure is as follows: If the current finished roll set has almost reached its nominal diameter, the working speed is reduced to 0 m / min over a predetermined ramp. Shortly before reaching standstill - when the standstill occurs, the actual diameter of the finished rolls naturally corresponds to the nominal diameter - the individual webs are cut off, the ends of which are still fixed on the respective rollers in the caster. Then, when the system is stationary, the finished customer roll set is ejected from the winding bed and a new set of tubes is introduced into the released winding bed - cf. eg DE 43 34 029 C2 , Only when this is done, a new winding process can begin. The person skilled in the art summarizes these processes under the term "set or throw change". It is clear that these set changes cost time and reduce the productivity of the slitters. To illustrate the negative impact, the following example: If a set change takes place on average every 6 minutes during reel cutting - this figure is quite practical - then there are already a considerable number of 240 set changes in 24-hour operation. Extrapolated to one year of operation, this results in about 85,000 small "production losses", resulting in a duration of 20 sec per set change annually to approx. 20 days "production interruption" added up.

Bezüglich des Standes der Technik wird auf DE 602 03 901 T2 verwiesen, bei dem ein Verfahren und eine Vorrichtung für einen Doppeltragwalzen-Rollenschneider beschrieben sind, bei dem eine der beiden Tagwalzen für den Setwechsel so bewegt wird, dass sich vorübergehend ein Abstand zwischen beiden Tragwalzen ergibt, der groß genug ist, um einen Satz neuer Wickelhülsen von unten durch den Spalt hindurch nach oben zu verlagern. Sobald der neue Hülsensatz den Spalt passiert hat, muss die zuvor bewegte Tragwalze natürlich in ihre ursprüngliche Position zurückbewegt werden.With respect to the prior art is on DE 602 03 901 T2 referenced in which a method and apparatus for a double carrier roll winder are described in which one of the two day rollers is moved for the set change, that temporarily results in a distance between the two support rollers, which is large enough to move a set of new cores from below through the gap upwards. Of course, once the new sleeve set has passed the gap, the previously moved carrier roll must be moved back to its original position.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren bzw. eine Vorrichtung der eingangs erwähnten Arten so weiterzubilden, dass die oben beschriebenen "Verlustzeiten" ohne größeren baulichen Aufwand weitgehend reduziert werden.The invention has the object of developing a method and a device of the aforementioned types so that the "loss times" described above are largely reduced without major construction effort.

Diese Aufgabe wird erfindungsgemäß bei dem Verfahren der eingangs genannten Art dadurch gelöst, dass man in den von den beiden Tragwalzen und dem laufenden Wickel begrenzten Raum die mindestens eine neue Hülse einbringt, frühestens sobald die geometrischen Verhältnisse diese Raumes und der Hülse das gestatten.This object is achieved in the method of the type mentioned fact that at least one new sleeve introduces into the space bounded by the two support rollers and the current winding, earliest once the geometric conditions allow this space and the sleeve.

Bei der Vorrichtung der eingangs beschriebenen Art wird die Aufgabe dadurch gelöst, dass in dem Zwickel der unterhalb des von dem laufenden Wickel und den Tragwalzen gebildeten begrenzten Raums eine maschinenbreite Einrichtung angeordnet ist, die durch den unveränderbaren Spalt zwischen der Tragwalzen hindurch in besagten Raum hinein- bzw. aus dem besagten Raum herausbewegbar ist.In the device of the type described above, the object is achieved in that in the gusset of below the formed by the current winding and the support rollers limited space a machine-wide device is arranged, which go through the unchangeable gap between the support rollers in said space or moved out of said space.

Nach der Erfindung wird im Zuge des Set-Wechsels ein neuer Satz Wickelhülsen bereits zu einem Zeitpunkt in das Wickelbett eingebracht, in dem der aktuelle Satz Fertigrollen in voller Aufwicklung befindlich ist. Voraussetzung für das Einbringen der Hülsen ist natürlich, dass der von den beiden Tragwalzen und dem laufenden Wickel begrenzten Raum so groß geworden ist, dass er die neuen Hülsen aufzunehmen vermag. Dieser Zustand ist zu Beginn eines jeden Wickelvorgangs noch nicht gegeben, tritt aber zwangsläufig ein, sobald der Durchmesser der aktuell gewickelten Rollen einen bestimmten Durchmesser erreicht hat. Ab sofort wird dann eine in dem Zwickel, der unterhalb des von dem laufenden Wickel ( ) und den Tragwalzen gebildeten begrenzten Raumes eine maschinenbreite Einrichtung angeordnet ist, durch den unveränderbaren Spalt zwischen der Tragwalzen hindurch in besagten Raum geschoben, wo ein an dieser Einrichtung angebrachtes und unten näher erläutertes Element nach seiner Umformung in der Lage ist, den neuen Hülsensatz abzustützen. Für die Beschickung dieses tragenden Elementes, das man auch als Hülsenrinne bezeichnen kann, mit Hülsen gibt es verschiedene bekannte Mittel, auf deren Darstellung hier verzichtet werden kann. Es versteht sich, dass die Vorrichtung aus ihrer eben beschriebenen Arbeitsstellung auf umgekehrtem Weg wieder in ihre Ausgangsposition zurückkehrt, sobald die Hülsen keiner Unterstützung durch sie mehr bedürfen, weil sie im Zuge des neuen Wickelprozesses und ihrer dadurch bewirkten Durchmesserzunahme nunmehr von den Tragwalzen gehalten werden.According to the invention, a new set of winding tubes is already introduced at a time in the winding bed in the course of the set change, in which the current set of finished rolls is in full winding. The prerequisite for the insertion of the sleeves is, of course, that of the two support rollers and the current winding limited space has become so large that he is able to accommodate the new sleeves. This condition is not given at the beginning of each winding process, but inevitably occurs as soon as the diameter of the currently wound rolls has reached a certain diameter. From now on in the gusset, which is below the formed by the current winding () and the support rollers limited space a machine-wide means is pushed through the invariable gap between the support rollers through said space, where attached to this device and below explained element after its transformation is able to support the new sleeve set. For the loading of this supporting element, which can also be described as a sleeve groove, with sleeves, there are various known means, the representation of which can be dispensed with here. It is understood that the device returns from its working position just described in the opposite way back to its original position as soon as the sleeves no longer require support through them, because they are now held by the support rollers in the course of the new winding process and thereby caused diameter increase.

Vorteilhafte Weiterbildungen ergeben sich aus den jeweiligen Unteransprüchen.Advantageous developments emerge from the respective subclaims.

Die in Fig. 1 dargestellte Rollenschneidmaschine (1) umfasst eine Abrollung (2), in der eine volle sogenannte Mutterrolle (3) drehbar gelagert ist, von der eine ggfs. bis zu 11.000 mm breite Bahn (4) abgezogen und anschließend in einer Längsschneidvorrichtung (5) in Einzelbahnen aufgeteilt wird. Diese Einzelbahnen werden sodann in einem aus zwei Tragwalzen (6, 7) bestehenden Wickelbett (8) zugeführt, in dem sie auf Wickelhülsen (12) zu Fertigrollen (9) aufgewickelt werden. Nach der Fig. laufen die Einzelbahnen durch den Spalt (10) zwischen den beiden Tragwalzen (6, 7) hindurch auf die Hülsen auf; dieser Warenlauf wird als "Zufuhr von unten" bezeichnet. Es sind aber auch abweichende Bahnführungen bekannt, bei denen die Einzelbahnen zunächst eine der beiden Tragwalzen (6 oder 7) umschlingen, um dann "von oben" in den Nip zwischen den Hülsen und der jeweiligen Tragwalze einzutreten. Während des Wickelprozesses wird der Hülsen/Einzelrollen-Satz von zwei, in die randständigen Hülsen- bzw. Einzelrollen/Wickel eingreifenden, hier nicht dargestellten Führungsköpfen gehalten. Auch eine Andruckwalze (11) ist vorgesehen, die den Einzelrollensatz zumindest zu Beginn des Wickelprozesses in das Wickelbett (8) drückt. Erfindungsgemäß ist die Rollenschneidmaschine (1) schließlich noch mit einer Einrichtung (14) ausgestattet, die dem Hülsenhandling dient und die Fig. 3 und Fig. 4 näher dargestellt ist.In the Fig. 1 shown slitter (1) comprises a roll (2) in which a full so-called mother roll (3) is rotatably mounted, deducted from the possibly. Up to 11,000 mm wide web (4) and then in a longitudinal cutting device (5) in single tracks is split. These individual webs are then fed into a winding bed (8) consisting of two support rollers (6, 7), in which they are wound on reel sleeves (12) into finished rolls (9). According to the figure, the single webs run through the gap (10) between the two support rollers (6, 7) on the sleeves; this run is referred to as "feed from below". But there are also different web guides are known in which the individual webs initially wrap around one of the two support rollers (6 or 7), in order then to enter "from above" in the nip between the sleeves and the respective support roller. During the winding process, the sleeves / single rolls set of two, in the marginal sleeve or individual roles / winding engaging, not shown here guide heads held. Also, a pressure roller (11) is provided, which presses the single roller set at least at the beginning of the winding process in the winding bed (8). According to the invention, the slitter-winder (1) is finally equipped with a device (14), which serves the sleeve handling and the Fig. 3 and Fig. 4 is shown in more detail.

Der Vergleich der zumindest der Größenordnung nach korrekt wiedergegebenen Durchmesser von Mutterrolle und Fertigrollen macht übrigens deutlich, dass sich aus ein und derselben Mutterrolle mehrere Sätze Fertigrollen erzeugen lassen.Incidentally, the comparison of the diameter of mother roll and finished rolls, which is at least the correct order of magnitude, makes it clear that several sets of finished rolls can be produced from one and the same mother roll.

Die in Fig. 2 veranschaulichte Situation zeigt die Verhältnisse, die herrschen müssen, damit die Rollenschneidmaschine bereits bei fortlaufendem Wickelprozess mit einem Satz neuer Wickelhülsen beschickt werden kann. Basis sind Abmessungen, wie sie aus der Praxis bekannt sind. Danach ist das Einschieben von Hülsen (12) mit einem Außendurchmesser von 120 mm bei Tragwalzen (6, 7) mit einem Durchmesser von jeweils 1.000 und einem Achsabstand von 1.020 mm erst möglich, wenn der Durchmesser der in Aufrollung befindlichen Fertigrollen (9) einen Durchmesser von 950 mm überschritten hat - der Enddurchmesser ist vorliegenden mit 1.440 mm angenommen.In the Fig. 2 illustrated situation shows the conditions that must prevail so that the slitter can already be fed in the ongoing winding process with a set of new cores. Basis are dimensions, as they are known in practice. Thereafter, the insertion of sleeves (12) with an outer diameter of 120 mm in support rollers (6, 7) with a diameter of 1,000 and a center distance of 1,020 mm only possible when the diameter of the rolling rolls located in rolling (9) has a diameter 950 mm - the final diameter is assumed to be 1.440 mm.

In Fig. 3 ist die erfindungsgemäße Vorrichtung in ihrer Ausgangsposition dargestellt. Die Einrichtung (14), die später eine Hülsenrinne (18) bilden soll, ist im unteren Zwickel zwischen den Tragwalzen (6, 7) angeordnet. Sie besteht aus einem in X-Richtung maschinenbreiten und in Y-Richtung schmalen (Abmessung vorzugsweise kleiner als 40 mm) Teil, an dessen Oberkante (15) ein Element (16) angebracht, das in X-Richtung ebenfalls maschinenbreit ist und sich in Y-Richtung gleichfalls höchstens bis zu beispielsweise 40 mm ausdehnt. Aus dieser Stellung ist die Einrichtung (14) auf nicht näher dargestellte Weise vertikal derart verfahrbar, dass das Element (16) durch den unveränderbaren Spalt (10) zwischen den beiden Tragwalzen (6, 7) hindurch in den oberen Zwickel geschoben werden, um dort "ausgebreitet" zu werden. Das besagte Element (14) besteht aus einem an einer gemeinsamen Längsachse scharnierartig mit der Einrichtung (14) verbundenen Leistenpaar (17). Diese Leisten liegen hier vertikal dicht nebeneinander, sind mit nicht gesondert dargestellten Mitteln aber auch aus ihrer vertikalen Lage in eine horizontale schwenkbar.In Fig. 3 the device according to the invention is shown in its initial position. The device (14), which is to form a sleeve groove (18) later, is arranged in the lower gusset between the support rollers (6, 7). It consists of a machine-width in the X-direction and narrow in the Y-direction (dimension preferably less than 40 mm) part, at the upper edge (15) mounted an element (16) which is also machine width in the X direction and in Y Direction also extends at most up to, for example, 40 mm. From this position, the device (14) in a manner not shown vertically movable so that the element (16) through the invariable gap (10) between the two support rollers (6, 7) are pushed through in the upper gusset to there to be "spread out". Said element (14) consists of a hinge pair (17) hingedly connected to the device (14) on a common longitudinal axis. These strips are here vertically close together, are not shown separately means but also from its vertical position in a horizontal swivel.

Fig. 4 schließlich zeigt die Vorrichtung in ihrer Arbeitsstellung im oberen Zwickel zwischen den beiden Tragwalzen (6, 7). Hier sind die Leisten (17), die in Fig. 3 in zusammengeklapptem Zustand erscheinen, durch Verschwenken "ausgespreizt", so dass sie jetzt eine Auflagefläche (18) bildet, die die Hülsen abzustützen vermag. Es versteht sich, dass die Leistenpaar-Lösung nur eine Variante unter vielen anderen gleichwirkenden Lösungen ist; denkbar sind daneben z.B. teleskopartig sich nach links und rechts ausbreitende Teile bzw. eine schlauchartige Vorrichtung, die nach Passieren des Spaltes mittels eines Fluids ausbreitbar ist. Fig. 4 Finally, the device in its working position in the upper gusset between the two support rollers (6, 7). Here are the strips (17) that are in Fig. 3 appear in the folded state, by spreading "spread" so that it now forms a support surface (18) which is able to support the sleeves. It is understood that the bar pair solution is only one variant among many other equally effective solutions; next to it, for example, telescopically extend to the left and right spreading parts or a hose-like device, which is spreadable after passing through the gap by means of a fluid.

Fig. 5 Diese einen Ausschnitt aus Fig. 3 wiedergebende vergrößerte Darstellung dient lediglich der besseren Veranschaulichung und bedarf deshalb keines eigenen Kommentars. Fig. 5 This one cut out Fig. 3 reproducing magnified representation is merely a better illustration and therefore requires no own commentary.

Fig. 6 Diese einen Ausschnitt aus Fig. 4 wiedergebende vergrößerte Darstellung dient ebenfalls nur einer besseren Veranschaulichung, so dass auf eine eigene Erläuterung verzichtet werden kann. Fig. 6 This one cut out Fig. 4 reproduced enlarged representation also serves only a better illustration, so that can be dispensed with a separate explanation.
